The In the lower portion of the casing, there are lostrips 19 and 20 are permanently secured to the cated a plurality of shock-absorbing arch-shaped rubber top member 27, as indicated by the rubber members of sponge rubber that are substantially cement 28. These strips are also permanently sesemi-circular in extent, and located in the center cured on their lower surfaces to the transverse line of the casing. These units, or shock-absorb strip 9 by means of the rubber cement 29. ing arches are designed to take up any excessive The longitudinal strips 21, 22, and 23 are perdownward flexing of the suspended elastic strips, manently secured to the transverse strips 9 and under severe conditions. Located under the l0, at their upperV and lower'surfaces, by means 49 arches, is an inflatable member which may be of the rubber cement 30 and 31. The longitudinal varied, as to the air pressure, for restoring the strips 24, 25, and 26 are permanently secured, at normal condition of the supporting arches. their lower surfaces only, to the transverse strips Referring to the drawing:- 1l by means of the rubber cement, indicated at 32. Fig. 1 is a plan view, partially in section, show- It should be particularly observed that the loning portions of the framework broken away and gitudinal strips 24, and 26 are not secured to the longitudinal and transverse'elastic strips of the transverse strips 10, as indicated by the spaces sponge rubber broken away for illustrating the 33. This construction, therefore, permits the top arrangement of the same. member 27, longitudinal strips 19 and 20, transq Fig. 2 is a transverse sectional View on the verse strips 9 and 10, and the longitudinal strips N line 2-2 of Fig. 1, showing the elastic members 21, 22 Vand 23 to move freely upward and downsuspended at their ends, also the supporting ward, as a unit, when in use. The suspended conarches and the inatable member within the struction permits elasticity also, both in longituarches, and dinal and transverse directions of the framework. Fig. 3 is a longitudinal sectional view on the The longitudinal strips 24, 25, and 26, which are line 3--3 of Fig. 2, showing the longitudinal elastic permanently secured to the transverse strips `to be maintained in this member.

11, may move freely as a unit upward and downward, since they are suspended at the end portions 15. 34 indicates a plurality of arch-shaped members of sponge rubber, one of which is shown in section in Fig. 2. These members are located between the transverse strips 1l and the bottom plate 17, to which they are secured with the rubber cement 35, or otherwise. Their curved upper surfaces are in contact with the strips l1, indicated at 36. 37 indicates an'inatable member, which is locatedin the arch-shaped space on the under side of the members 34. The purpose of this inflatable member is to compensate for any loss of elasticity of the members 34, as the infiat-y ing tube 38 permits greater or less air pressure It should be stated that the longitudinal members 19, 20, 21, 22, 23, 24, 25 and 26 are fixedly secured to the end members 7', 5', 6', 3 and 4'. A suitable upholstered covering is indicated at 39.

It will be seen, from this description, that I have produced a multiplex automobile seat, which involves the principle of supporting the interior seat construction at its ends, or in other words, the longitudinal and transverse members of sponge rubber are suspended, or supported, only from their ends on the casing, 'thus permitting a free upward and downward movement of the cushion, when in use.

What I claim is:-

1. A multiex automobile seat comprising a suitable framework having side, end and bottom portions, a plurality of transverse and longitudinal elastic members suspended at their ends on the framework, means permanently securing a plurality of the transverse and longitudinal elastic members together in the upper portion of the framework and also permanently securing a plurality of the transverse and longitudinal members in the lower part of the framework together, but with a space between said upper and lower members being left free and unobstructed whereby the two sets of said members may have free upward and downward movement.

2. A multiiiex automobile seat comprising a suitable framework having side, end and bottom portions, a plurality of transverse and longitudinal elastic members suspended at their ends on the framework, means permanently securing a plurality of the transverse and longitudinal elastic members together in the upper portion of the framework and also permanently securing a plurality of the transverse and longitudinal members in the lower part of the framework together, but with a space between said upper and lower members being left free and unobstructed whereby the two sets of said members may have free upward and downward movement, and a plurality of arch-shaped members of elastic material located between the lowermost series of said elastic and transverse members and the bottom plate of the framework.

3. A seat construction for the purpose described comprising a supporting frame, the lower sides and end portions of the frame being of inelastic material and the upper sides and end portions being of elastic material, a plurality of elastic members secured at their ends only to the said portions of the supporting frame for permitting free upward and downward movement within the supporting frame, said elastic members crossing each other and being secured to each other at their crossing points, and means providing a pneumatic support between the bottom of the supporting frame and the said elastic members.

4. A cushion construction for the purpose described comprising a supporting frame, elastic members attached to the frame at their ends only and arranged parallel to the sides and ends of the said frame, means securing the elastic members together where they cross each other, a plurality of arch-shaped elastic members located below the said members for receiving abnormal shocks as described.

5. A cushion construction for the purpose described comprising a supporting frame, elastic members attached to the frame at their ends only and arranged parallel to the sides and ends of the said frame, means securing the elastic members together where they cross each other, a plurality of arch-shaped elastic members located below the said members for receiving abnormal shocks as described, and means for varying the compression effect of the arch-shaped members.
